Detailed Description

Polygon - Geographical polygon object. This class represents a draw object with polygon geometry, defined in geographical lat/lon coordinates. The polygon may consist of several "rings" where each ring is a closed polyone. The outer ring is the perimeter of the polygon and any inner rings will be holes.

The outer ring is taken to be ring #0 by convention, and if no ring is specified in the api methods, the outer ring is assumed.

Member Function Documentation

addPoint()

void Maria::Polygon::addPoint	(	const BasicGeoTypes::GeoPos &	p,
		int	ring = 0
	)

Append a new point to the given polygon ring.

Parameters

p	New point data.
ring	Ring index. If not specified, ring 0 (the outer perimeter) is assumed.

getNumPoints()

int Maria::Polygon::getNumPoints ( int  ring = 0 ) const

inline

Get number of points in the given polygon ring.

Parameters

ring	Ring index. If not specified, ring 0 (the outer perimeter) is assumed.

Returns

Number of points in the ring.

getNumRings()

int Maria::Polygon::getNumRings ( ) const

inline

Get number of polygon rings.

Returns

Number of rings in the polygon

getPoint()

BasicGeoTypes::GeoPos Maria::Polygon::getPoint	(	int	i,
		int	ring = 0
	)		const

Get a point from a given polygon ring.

Parameters

i	Point index the the polygon ring.
ring	Ring index. If not specified, ring 0 (the outer perimeter) is assumed.

Returns

A geo point for the given index.

getPosition()

BasicGeoTypes::GeoPos Maria::Polygon::getPosition ( ) const

overridevirtual

Get the origin of the draw object in geographical coordinates.

Implements Maria::DrawObject.

setPoint()

void Maria::Polygon::setPoint	(	int	i,
		const BasicGeoTypes::GeoPos &	p,
		int	ring = 0
	)

Set a point in the given polygon ring.

Parameters

i	Point index the the polygon ring.
p	New point data.
ring	Ring index. If not specified, ring 0 (the outer perimeter) is assumed.

setPosition()

void Maria::Polygon::setPosition ( const BasicGeoTypes::GeoPos &  pos )

overridevirtual

Set origin of the draw object at the given position.

Parameters

pos	Geographical position of the draw object.

Implements Maria::DrawObject.
